Aball is moving at a speed of 5 mi/h along a frictionless surface. it will continue moving at this speed as long as (select all that apply)
a) something keeps pushing it because it requires a force to continue its motion
b) balanced forces act up on it because an unbalanced force will change its motion
c) something keeps pulling it because it requires a force to continue its motion
d) no forces act upon it because it’s inertia will allow it to continue moving at a constant velocity

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
